TO ALL WI-IOM IT MAY CONCERNE Be it known that I, EZRA PECK, of the city of Chicago, county of Cook, State of Illinois, have invented a i new and useful Improvement in Plows; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and the letters marked thereon, making a part of this specification.

v Figure 1 is a side view of my invention, in which Ais the beam; o is the slotted concave support of the beam; C is the pivot or point on which the be'am may be turned when desired to cut more or less land; B is the bolt, which fastens the beam to the slotted concave support o; b Zi bare the rivets which fasten the'two parts of the beam, A and K, together; z'is the wheel-Coulter, and u is the standard or support of the same. l

Figure 2`is a top'fview of the same, showing a plan or cross-section of the beam at the point of its attachment to the plow; also a plan ofthe slotted concave supporto, and bolt B.

Figure 3 is a cross-section of the beam, lshowing the method of fastening the two parts ofthe beam A and K together. v

, Figure 4 is a top view of a portion of the beam A, showing the method of operating the coulter.A u is the standard or support of the coulter z',-

is theclip or clasp ofthe same'. i

Figure 5 is a plan or vertical cross-section of the beam and coulter.

Like letters refer to the same parts in all views. e

The nature ofvmy invention consists in constructing a plow-beam from sheet metal, in such a manner' that whilst the beam is arched or curved, so as to form the standard of the plow, its crosssection will be the same as shown in iig. 3, or some equivalent form, with the ilangesrE E to keep it from buckling, and, -to give itfaddivtional strength; and to serve as a means for fastening on the strip K, the additional strip or part K' is firmly riveted to the flanges E E, which give great strength, enabling the beam to stand a greater cross-strain; it also acts as a brace, making the beam very stiff and rigid, and preventing that/elasticity which is so detrimental to Vthe good working of theplow'f..` it also prevents the beam from twisting in the upright portions of the same.

Also, in the method of attaching the beam to the plow by means ofthe slotted concave support o, as shown in fig. 2. p

Also, in the peculiar method of adjusting the wheel-Coulter t', by means of rounding or angling the-inner face of the coulterattachme'nts or standard u, the clasp/.7' controlling its cutting-angle, by drawing up one nut, and loosening the other when desired to cut more or less land. v

To enable those skilled in the art to make and use my invention, I will proceed tovdescribe its construction and operation. i y

The beam A is made from sheet metal by bending first in the form shown in fig. 3, after which it is again heated to a whiteheat, and pressed between two dies ofthe required form, or in any other of the known mcthods for working iron. After thus forming the main portion of the beam, the strip K may be constructed in asimilar manner, and can also be stamped in the U-form, if desired. Then, the two Vparts may be firmly joined together by means of rivets, or otherwise. The form of the cross-section of this beam can be varied to suit the taste of the maker. l

The slotted concave support is constructed as shown ato, iig. 2, the bolt B passing through the slot in the support; thence through the beam, as vvseen in figs. l and 2, the nut boing on the back of the beam A. The bea'm K is made corwex,.andl the. support concave at their point of attachment, and the support is` firmly fastened to the mould-board z ofthe plow, and the beam is adjusted atthe proper angle to cut more or less land by turning it on the pivot or centre C, iig. l, the slot in the support permitting the bolt B to move with the beam, the convex form giving'itI at all times a good bearing when the beam is properly adjusted. The nut on the bolt B is screwed up tight, thus holding the beam irmly to its place. y

To fasten a Coulter to `this beam, a cast block is used to fill up the beam to a perpendicular face. The standard u, or whatever support may be used for the wheel z'is rounded, or-convexed, or concaved, or angled,

as shown at u, yg. 4. The cast block can be dispensed with in all beams having a perpendicular face or bearing, or the block can be made convex or concave, to correspond with the vWheel-ettacllment u; but I consider the form shown at u, g. 4, the preferable way. The clasp or clip j is tted on the same, or any clip, by passing over the broad flat back ,of the standard u, g. l, and should be well ttedat the angles; tben, When'it is desired to change the cut ofthe coulter z', we have-only to loosen one nut of the clasp j and tighten up the other, which will rock the standard u on its centre, thus changing the cutting-angle, to cut more or less land.

What I'clnitn as my invention, and desire to secure by Letters -Patent, therefore,- is- 1. A hollow sheet-metal beam, when constructed with the flanges E E, as set forth, and for the-purpose specified.

2. Constructing a hollow plow-beam by riveting or otherwise properly fastening together the two parts, A. and K, or their equivalent, for the purpose specified.

3.` Constructing a hollow plow-standard and beam, curved and bent vin one eontinuouspiece, directly from sheet metal, in the manner and for the purpose specified, es a. new article of manufacture.

4. The slotted concave support, in combination with the beam A. and mould-board e, all arranged as set forth.

5. Rounding or angling the inner bearing or face ofthe Coulter-standard u, when used in connection with the clasp j, in the manner and for the purpose specified.

6. The beam A, strip K, flanges E E, slotted support o, and mould-board e, all constructed and arranged as set forth.
